{"id":"CVE-2026-53279","summary":"drm/gma500/oaktrail_lvds: fix hang on init failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/gma500/oaktrail_lvds: fix hang on init failure\n\nThe LVDS init code looks up an I2C adapter using i2c_get_adapter() and\ntries to read the EDID before falling back to allocating and registering\nits own adapter.\n\nThe error handling does not separate these cases so on a late init\nfailure it will try to deregister and free also an adapter that had\npreviously been registered. Since i2c_get_adapter() takes another\nreference to the adapter, deregistration hangs indefinitely while\nwaiting for the reference to be released.\n\nFix this by only destroying adapters allocated during LVDS init on\nerrors.","modified":"2026-07-09T03:51:29.490712627Z","published":"2026-06-26T19:40:41.489Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53279.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/4e04b564c005c9900643c56656d751ad677889be"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5fe9f505d8578852c30668567bc3ce52e776e8c7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/657a091ab6d01d0091b77660c75cfed573c9a53e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7877f7e231a8bd5c817af1491276550a5e195cd7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ab9256936b58eb178caddcf5b5b1638f079909d2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f6fc44af3bbd5ab0fb6bdec6f47decca11b38425"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53279.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53279"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"a57ebfc0b4da16a3f36bfebb158198aab3e340f8"},{"fixed":"5fe9f505d8578852c30668567bc3ce52e776e8c7"},{"fixed":"4e04b564c005c9900643c56656d751ad677889be"},{"fixed":"7877f7e231a8bd5c817af1491276550a5e195cd7"},{"fixed":"ab9256936b58eb178caddcf5b5b1638f079909d2"},{"fixed":"f6fc44af3bbd5ab0fb6bdec6f47decca11b38425"},{"fixed":"657a091ab6d01d0091b77660c75cfed573c9a53e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53279.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.0.0"},{"fixed":"6.1.175"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.141"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.91"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.33"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53279.json"}}],"schema_version":"1.7.5"}
